## Summary description

StarTech 3 m DB9 RS232 straight-through serial cable (male to female) in black. A 3-meter cable with DB-9 connectors for RS232 serial communication, suitable for connecting legacy serial devices, modems, industrial equipment and POS systems. Single-pack cable, lightweight and packaged for retail.

## Long description

The StarTech 3 m DB9 RS232 straight-through serial cable (male to female) in black provides a reliable wired connection for RS232-enabled devices. With a 3-meter length and DB9 male-to-female connectors, this cable extends serial links between computers, modems, industrial controllers and peripheral devices while maintaining signal integrity for standard RS232 communication.
Advantages
This serial extension cable offers a straight-through DB9 pinout that preserves device-to-device signaling without rewiring or adapters. The 3 m length gives additional reach to position equipment conveniently, and the cable is constructed with shielding and durable connector housings to reduce electromagnetic interference and wear from repeated plugging. Designed for straightforward installation, the cable supports standard RS232 data rates and is lightweight for retail packaging and transport.
Suitable for
Connecting legacy RS232 devices such as modems and serial printers
Extending serial connections between PCs and industrial controllers
Point-of-sale (POS) peripherals and barcode scanners that use DB9 serial ports
Laboratory and test equipment requiring stable RS232 links
Key specifications
Cable length: 3 meters
Connector type: DB9 male to DB9 female, straight-through pinout
Color: black
Interface standard: RS232 serial communication
Shielding: foil/braid shielding to reduce EMI (electromagnetic interference)
Construction: molded connector housings for strain relief and durability
How to use
Connect the DB9 male end to the DB9 female serial port on your host device and the DB9 female end to the DB9 male port on the peripheral. Ensure connectors are fully seated and secure any captive screws if present to maintain a stable mechanical connection. Confirm serial port settings (baud rate, parity, stop bits, flow control) on both devices match for proper communication. For longer installations, route the cable away from high-voltage power lines or sources of strong interference.
Usage recommendations
For best performance, use this cable for short- to medium-distance RS232 connections up to 3 m and avoid bundling with heavy power cabling. When installing in industrial environments, verify grounding and shielding practices to minimize EMI and consider using ferrite cores if additional suppression is needed.
